RADIATOR HEATER.

Application mea August as, 1925. serialpm. 52,709.l

This' invention relates to a radiator heater,`

and particularly to la construction adapted for application to an automobile radiator for the purpose of heating the water therein independent of the engine whenever found necessary or desirable. y

In previous constructions of this character the heaters used have been so slow in" action' that considerable time was required tose" cure suiiicient increase in temperaturein the. water for the proper startin andoperation e of the` engine, particular yl under cold weather conditions. I have therefore found it desirable to provide an improved type of l5 water heaterby which the temperature of the liquid may be uickl -raised and as a considerable body o liquld is involved this reduces the vtime necessary to securing` a proper temperature for the starting of the engine.

The heater is also so constructed and conf nected as to be always ready for operation by its circulating connection with the radiator and does not affect the ordinary enginel circulation when the automobile is under operation. l

In the previous types-of radiator heaters it has been more or less inconvenient to `ignite the same, requiring in some cases a pilot burner, and the control of the burner has not been accessible to the operator of the machine at the dashboard connection.

I have therefore provided means by which an electric ignitor cooperates with the wick of the heater so as to avoid the necessity of maintaining a constant or pilot light and also rovidmg 'means by which a spark may support for the burner.

be dlrectly applied to the wick for its immediate ignition when desired. Means are 4 also provided for the regulation of thev wick to control the position thereof and the consequentheating capacity of the burner` relal v `applicable to various uses such as the heat tive to the boiler disposed in the flue communicating therewith.

The invention has for an object lto provide an improved type of heater having a water space with a substantially corrugatedradiating wall, said space being in circulating connection with a radiator and the flue within said corrugated wall beingin communication with a heating burner.

Another object of the invention is to provide a tubular water heater in circulation with theradiator and having al heating chamberdisposed above the discharge for the products of combustion and connected with the tubular heater by a series of conducting tubes.

A further object of the invention is to provide an' electric connection for igniting a heater and comprising a sparking coil hav'- ingaia-seconda-A ci'rcuit connectedfv-twith a contact dispose at the point of ignition of the heater and insulated from the body thereof, together with a return circuit'from the fuel receptacle ofv the heater which is otherwise insulated from the enigine structure and casing.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

This construction lof radiator heater is fio' rugationyshown involves the ribs 2O of out-l Awardly,increasing diameter and connectedv and aninne'r substantially.corrugated shell 12 forming'an intermediatewater space 13 which isin communication with a radiator 15 at its' lowerportionl by means of any' desired form .of connection as shownat 16.

The'discharge from-theheater is likewise connected with the upper portion yof the rad'faftor by means of a connection as at 17. The construction of the substantially cor, rugated inner wall of the water chamber providesthe maximum radiating surface in communication with theproducts of 'combustion from the heater` -18 which pass upward through the flue 19|.formed by the corrugated wall. The specific form of -corl l,at/their base by which the most efficient f pipesor tubes 22 extend upon arcuate'lines` to a superheater 23 which is supported thereheating is secured. 20

The water space. discharge end of the heater to form a cham ber 21 from which a series of. connecting directly above the discharge from the lvertical flue 19. 'The under surface of this heater -is curved and causes the products of combustion to be deflected outwardly in oposite directions while the liquid passing trough the tubes 22 and the chamber l23 becomes super-heated and isdischarged from the latter at -24-.into the return connectien 17 to'the'radiator. This radiator is connected with the engine 25 in theusual mannen as indicated by dotted lines in Figure 1, and by heating the water therein to establish a circulatlon the `engine is preliminarily heated before being started.'

For the purpose of applying heat to the heater various forms of burners may be used, a convenient type being that of-an oil burner as shown at 18, The wick 26 of suchv a burner extends into the fuel receptacle 27 v in the usual manner and surrounds the air intake 28 common to this type of burner. The heater 10 is supported above the burner by means of a casing v29 which if desired may be provided wit-h glazed sight openings 30 and a closure or door' 31 for access to the burner. The wick of the burner is. adapted to be raised and lowered to control the degree of heat generated therefrom by means of a dashboard connection which comprises essentially a crank lever 32 mounted uponl the receptacle and having its arm,l 33 connected with the wick raising rod 34,l From this lever an o erating rod .35 extends to the dash 36 o connectedV to a hand leverl 37 l adjustably operating upon an arcuate sector 38. By this means al1-accurate and delicate-.adjustment of 'the'wick may be effected to' secure the desired rapidity of heating at the burner.

vSince such a-burner is not continuously 13 is enlarged at the upper the machine where it isl u'se'd, I have provided electrical means for iguiting .the .wick or other form of burner and controlled from the instrumentboard. This means comprises a sparking or transformer coil 4,0..y-l-iaving its primary circuit connected to a battery 41 bya leader" 42 and the opposite terminalef its primary being V extended by a line 43 to a switch 44 upon the instrument board 45. The return circuit 46 from this switch extends to they opposite side of the battery 41. The secondary circuit from the coil comprises the line 47 which is connected by means. of aterminal 48 in circuititherewithyand'mounted in an insulated block or base 49 within the casing ing blocks 52 and such a support is of a yielding character so as to prevent splashing or loss ofthe fuel and also form a yielding support for the burner. prises the posts 53 .extendin from the blocks 52 and .carrying screw ro s 54 which pass through the upper end of an 'enclosing sleeve 55 within which a coil supporting spring 56 is disposed in contact with the upper face of the post 53. This sleeve is 4secured-to the Such support comreceptacle 27 at substantially the four cor-n ners thereof.

The general operationpof the invention will be apparent from the foregoing description from which it will be'seen that the heater provides a simple land convenient means for quickly raising the engine temperature when it is desired to Start a cold engine, thus greatly economizing in the time required and 'in the stra-in upon the battery incident to repeated starting. A heater of .this character is only practical and eilicientA in accordance with the rapidity vwith which the temperature of the water canvbe raised,

and therefore special designs have been embodied to superheat the water and establish a'circu'lation thereof from the heater to the engine in the shortest possible time. It will be obvious that the connections for the reg` ulati'on of the burner and for the ignition thereof' from the dashboard forni` a very convenient means for its control and avoid ,the necessity of opening the engine hood or coming into direct contact withthe heater.4

Whileythe specific construction of the sev-j' eral parts has been' shown and described,v

the invention is not confined4 thereto as 130 invention as defined by the appended claims. Having thus described my invention,

'what I claim as new and desire to secure by Letters Patent is:

1. In a'radiator heater, a burner and fuel receptacle, insulated supports for the receptacle, a sparking igniter havin a terminal mounted in an insulatinor b y surrounding the burner and terminating lat the ignition point of said burner, a burner casing carried by said insulating body, anda terminal upon said receptacle for establishing circuit throu h the burner independentof- `the support fg or the Vfuel receptacle.

2. I n a radiator heater, avburner and fuel receptacle, insulated blocks having posts with interposed springs for supporting said' receptacle, a sparking ignitor having an insulated terminal adjacent said burner and a terminal upon said receptacle, andmeans operable from a'remote point for controlling said burner. f
